The details for the Windows 8 version were revealed on the official Halo Waypoint site with an August 29th release availability. It’s not clear if the Windows Phone 8 version will be updated at the same time, though presumably they will be tied closely together. That version for Windows Phone 8 should also bring support for 512MB devices, as previously reported.

So what can users expect? There’s three big new features here: new missions, new achievements and Xbox 360 joystick support.

Operation Hydra including 5 new missions

New Achievements (50 points) including Archeology, Silvertip, Tour of duty, A for Effort and Vidmaster Challenge 2.0

Support for Xbox 360 wired controllers – We knew this was coming from our earlier coverage, but now it’s confirmed that users will be able to plug in their Xbox 360 controller to their Surface Pro or desktop to get a new way to interact with the game

Overall, it sounds like a pretty comprehensive update for such an A-list title. We’ll keep an eye out for the corresponding Windows Phone 8 version as well, especially for those with 512MB devices.

RT has all those drivers from Windows 8. It works with printers, mouse, keyboards, etc....The IE browser is almost a clone from Windows 8. It will play pretty much any website with adobe flash videos. Pretty awesome for watching movies.

I hope, should they update the WP8 version, that they address the issue of how much room it takes to install the damned thing. It's a 700mb game that takes reportedly around 4gb free space to install. For the love of God why? Why does it need near six times it's own size to install?
I have yet to be able to install it because I have cleared everything I possibly can out of my Lumia 820, the vast majority of my games and pretty much every app that can be deleted, cleared my internet history, successfully flushed out the "other" folder, and still I only have 3.2gb. I'm bending over backwards to give you my money Microsoft, and I can't. Please sort this out. It's ludicrous.

Hopefully they will keep improving the game. It is monsterously huge though. I wish the core game shell was a download, with the ability to download/remove individual missions, kind of like how Here Maps lets you install/remove individual maps.
